@jariza this is what I did, however I am curious to know if he was able to resolve the SSL error. I am not using a multi domain SSL right now so my second domain throws an error. I'm using two regular SSLs, so the second Domain believes the server domain is my original domain and it says "Site not trusted"..

As far as I know, unless you use subdomains for each PrestaShop site and WildCard Certificates you will need to use a different certificate for each domain since the domain in the certificate and the URL will be different and the browser would consider it as "Not Trusted".
